Question. Most suggest putting the main support block about 70-75% the distance up the mast between the masthead and boom gooseneck. Some suggest its good to put it under the spreader about 6-8 away from mast to minimize chafe and noise of lines on mast. Both these conditions can be met with double spreaders.
My boat has single spreaders about half way between gooseneck and masthead. So with a 30' luff length, that puts the main block only about 15-16' above the gooseneck. Will this angle create problems or should I go ahead and mount the block to the mast above the spreaders.
And if one puts the main block on the mast above the spreaders, isnt it going to chafe on the spreader on the way down?
Seems like most the angular issues occur up high and by the time you get down near the boom, where its most important, theres not much difference.
When I setup the new lazy jacks on my boat, I wrote about it here. The line doesn't chafe much on the spreader because of the angles involved and the padeye for the block should be towards the aft side of the mast.

You can see the setup in this image:

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
